The required time from the station to the disembarking station, the departure time of the boarding station, the arrival time of the disembarking station, etc. are selected and set. However, when the departure time and the arrival time are selectively set, the actual time of the clock inside the mobile terminal 5 is compared with the vehicle operation timetable included in the vehicle operation information, and the optimum departure and arrival time is displayed on the display unit. .

Next, before and after boarding, the overpass prevention function is executed. If you execute the anti-override function before and after boarding, the setting will be done in a busy time, so you may make an incorrect operation and the original function will not work, or you may be distracted by the setting In order to prevent (falling down or harming others), even if there is a difference between the actual time and the time when the anti-passover function is executed (time difference between actual time and setting time), especially from the boarding station Even if the time required to get off the station is set, the original function shall operate. It should be noted that this time difference between the actual time and the setting time is absorbed within a permissible numerical value range for mutual determination that an approaching station is approaching. Further, this allowable numerical value range can be set in advance by the submenu of the overpass prevention function.

While the operating vehicle 2 is proceeding from the starting station to the terminating station, the GPS receiver 3 mounted on the operating vehicle 2 receives the radio waves transmitted from a plurality of GPS satellites 1 and the time is constant. The changing position information is transmitted to the mobile terminal 5 carried by the passenger by the short-range wireless communication device 4.

The mobile terminal 5 receives the vehicle position information moment by moment, but it is determined by the process described below that the alighting station is near, and sound (voice, music), light, or vibration is given by the notification means of the mobile terminal 5. Notify passengers that they are approaching or getting off at the station.

(1) The actual time of the clock inside the portable terminal 5 is compared with the preset time required from the boarding station to the exit station or the arrival time at the exit station, and the result is within the preset allowable numerical value range. If it is determined that the disembarkation station is close, it informs that the disembarkation station is approaching or is the disembarkation station (time matching).

(2) When the position information of the disembarking station recorded inside the mobile terminal 5 and the vehicle position information that the mobile terminal 5 receives from time to time are sequentially collated, and within the preset allowable numerical range. , It is judged that the disembarking station is near, and the disembarking station is approaching or the disembarking station is notified (position matching). At this time, instead of always collating, the actual time of the clock inside the mobile terminal 5 is collated with the preset time required from the boarding station to the alighting station or the arrival time of the alighting station, and the preset time ( The position information can be verified from the time set before the arrival time at the alighting station as a reference) (condition verification).

(3) Position information of the starting station, passing station, passing point a, passing point b, passing point c, alighting station and ending station included in the vehicle operation information, and the portable terminal 5 receives from moment to moment. The vehicle position information is constantly collated, and the getting-off station is predicted and estimated from the vehicle position information that the mobile terminal 5 receives every moment, and the getting-off station is approached or the getting-off station is notified (prediction).

(4) Position information of each of the starting station, passing station, passing point a, passing point b, passing point c, alighting station and ending station included in the vehicle operation information, timetable (departure time) and mobile terminal 5
Constantly collates the vehicle position information and the time of the internal clock, which are received moment by moment, and compares them with each other (position information and required time, time) to determine whether or not the operating vehicle 2 is operating on time, and disembarks. It has a function to improve the accuracy of judging that it is a station (multiple matching).

(5) While the vehicle is in operation, the GPS receiver 3 cannot receive the radio waves transmitted from the plurality of GPS satellites 1,
If the location information cannot be obtained, the standard required time between the starting station, transit station, transit point a, transit point b, transit point c and the exit station included in the vehicle operation information, or between the station and transit point And a method of calculating the time of the clock inside the mobile terminal 5 to predict the alighting station, when the radio wave transmitted from the satellite can be received and the position information is obtained, the radio wave cannot be received and the position information is If there is no significant difference from the position information on the vehicle operating route from the mutual relationship with the position information before being no longer obtained, after that, the method of continuing to judge that it is approaching or getting off the station, If there is a difference, the predicting means is continued, and when the radio wave transmitted from the GPS satellite 1 is intermittently received or not received, the unclear operation mode is set as the position information of each station and the GP.
A method for specifying the position of the running vehicle 2 by mutual calculation from the position information obtained from the S function, the standard required time between each station or between the station and the passing point, and the time of the clock inside the mobile terminal, and this method and the prediction method. According to the result obtained from the above, when the position information of the exit station set in advance or the arrival time of the exit station is approximated, it is notified that the exit station is approaching or the exit station (composite verification).

In the above, as the route (station) information of the operating vehicle 2, the station name and position information of the starting station, the intermediate (passing) station and the ending station, and the information from the starting station to the intermediate (passing) station and the ending station Although it describes that vehicle operation information such as required time, arrival or passage time, etc. is downloaded from the content server to the mobile terminal 5 via the wide area wireless network 6, it is also operated in the "Manual setting" submenu of the anti-passover service function.

It is also possible to operate the GPS function of to acquire the position information of each station and set the position information of each station (self-learning function). However, since the position information may not be acquired even when the GPS function of the mobile terminal 5 is operated while the vehicle is stopped at each station,
If it cannot be acquired, it may be acquired outside the operating vehicle 2 or moved to a position where it can be acquired.

Regarding the vehicle operation information, the operation of the operation vehicle 2 has "up" and "down" with respect to the route, and two types of vehicle operation information arrays from the first station to the last station are required. When using the anti-override service function, the traveling vehicle 2 travels along the route in the "down" according to the arrangement (sequential arrangement), so it is used from the beginning of the vehicle operation information stored in the memory circuit of the mobile terminal 5, When the vehicle 2 is "up" to the route, the vehicle travels in the opposite direction to the "down" arrangement, so the vehicle is used from the stored vehicle operation information toward the beginning (reverse arrangement). .

When using the transit prevention service function, if "up" is not selected and set in the submenu of the transit prevention service function, and a boarding station and a getting-off station are set, the mutual relationship between both stations is It is possible to use the vehicle operation information by deciding whether it is the forward array or the reverse array from (the array of the vehicle operation information). In the present embodiment, the "downstream" array is a forward array, but on the contrary, the "downstream" array may be a reverse array, or a dedicated array for "upstream" and "downstream" may be provided.
